CI, alternative a confronto :-)

Continuous Integration - Know your opportunities

Continuous Integration in a nutshell

Continuous Integration (CI) is an important practice every team should adopt in order to detect defects and errors early and solve integration problems easily. Roughly speaking we may say that CI is a practice that allows the growth of solid software by giving greater confidence to the developers and better products to the final customers.

The concept behind CI is fairly simple: the codebase is owned by several developers that continuously integrate their changes to a common version control system. For each integration the system runs a predefined set of tasks automatically; these tasks may vary from running all the tests to building all the components.

Nomi

  • Tutte le variabili, costanti, funzioni, classi etc devono avere un nome significativo. Se il nome ha bisogno di un commento per essere spiegato non è abbastanza significativo.

  • Sono da evitare nomi che possano sviare dal vero significato della variabile

Internet Scale Services Checklist

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

Basic tenets

  • Does the design expect failures to happen regularly and handle them gracefully?
  • Have we kept things as simple as possible?

Generate ctags for Atom (or for any other reason) on Mac os X

Why?

Atom can automagically picks up any tags file in your current directory which enables you to:

  • shift+cmd+r search for any function in your project
  • alt+cmd+down GoTo a function declaration

How

Get brew if you don't already have it. Then:

brew install ctags
